A schematic diagram showing the essential parts of the 1st and 3rd m1 bodies, and Figure 4 shows the valve structure in exploded form. The cross-sectional views shown in Figures 5 to 10 show the various stages of valve disassembly using a remote control tool. Figures 5, 6, 9 and 10 are shown at the same angle as Figures 1 to 4. 7 and 8 are plan views.

Invention - Preferred forms for carrying out the invention First, the main structure constituting the valve will be explained.

First, FIG. 2 shows the valve body 1't-. The valve body 1 has four main parts! section, i.e. Two pipe couplings 2 are fixed to a pipe that is and a central sleeve or core 11, in which the movable parts of the valve are arranged.

The end fitting As has SS. Core 11 is from annular nut support WJ4#C The end attachment is done on the side of the tool 3. In this case, there are three VCs at the upper end of the core 11. A positioning bin 6 is attached. In addition, the four recesses 7 for the rods are also located in the main body 1' T! Cross 1iKK.

The contact between the core 11 and the other parts of the valve is firstly ensured by the core support surface 10; The core support surface 10 is a conical surface communicating with the hole of the pipe coupling 2, and also has a conical surface communicating with the hole of the pipe coupling 2. Guaranteed by an annular cage support surface 9 against the top of the body 1, said support ff1i9 terminates in front of the cylindrical cage hole 8.

The main body 1 includes a first structure, and 9 includes parts of the inner structure 20 shown in FIG. Enkata The structure 20 first consists of an operating member 21 that alternately opens and closes the valve. The operating member is The actuating member 21 and the The cage 22 is in contact with the cage 22 and has a ring (not shown).

The ring is made from an organic material, such as plastic, with a low fi coefficient. It will be done. Their lifespan is often much lower than that of the valve's metal components. They must then be replaced at relatively short intervals.

Cover 26 is connected to cage 22 via cap 32. Groove of cap 32 And a ring 29 arranged in the slot circle of the cage 22 is connected to the cage 22 and the cover 2. Six! ! This guarantees threading while allowing constant translation between these two parts. but However, their relative rotational movement is prevented by the set screw 27.

It was. The cover 26 has a 9fl opening. That is, these apertures 3 are for the positioning bin 6 of the main body 1, and 2 m is for the actuator 70 which will be described later. Although for positioning bins 76, these openings are not shown in their entirety here. most Later, the cover 26 has four accessory openings 35 (see FIGS. 7 and 8), which The actual aperture is designated 34 and the auxiliary aperture is designated 35. Mako cover 2 An internally chamfered local plate 28 is fixed to the local part of 6.

The operating member 21 consists of a spindle 37 that traverses the cap 32 and a cover 26. The end portion Vc of the sign is connected to a key or lens having a polygonal cross section by a locking screw 32. 30 is attached.

In addition, the valve has an M22 structure and the holding structure 40 shown in FIGS. 2 and 4. . The structure first consists of a support plate 41 for four rods 42; A nut 47Ki whose nut support surface 4 is movable within the tap hole of the support plate 41! do 1 circle of the body until it comes into contact with the support surface of the body 51 (via the annular support ring 50). It can be slid in the recess for the placed rod 7.

A plurality of rods 42 have chamfered ends 43 and one of the rods has a retaining structure. It is possible to have marks for precise angular positioning during the 40 lifts.

The rod also has a reduced diameter section 59f:V which is flush with the cover 26 during assembly of the valve. t, the lever portion 59 is limited by the lower release shoulder 45 and the upper locking shoulder 44. be done. In its lower part there is a guide which engages with the support plate 41 and which supports the support plate 4. angular guide with a flat section extended by a thread projecting beyond the lower surface of 1; A region 46 is provided.

The locking nut 61 makes it possible to lock the rod 42 onto the support plate 41. Retention The assembly 40 also includes special equipment, which will be described next.

The nut 47 has a sliding groove 49 in it, as can be seen in FIG. It has a hole 48 made. The end fitting hole 60 is made at the top of the nut 47 and has a large diameter. A nut hole 4 with a BIC support shoulder 58 connects it.

When the valve is assembled, the end fitting of the main body 1 ensures that the tool 3 only makes contact with the end fitting hole 60. The end fitting groove 5 is located directly below the support shoulder 58. In front of groove 5 is its inner diameter. However, in the end mounting, a retaining ring 57 larger than the diameter of the tool 30 is attached, so that this The holding structure 40 with the parts previously described is not supported by the body 1 and is not heavy. fall (by the action of force).

Thus, a substantially cylindrical cup 52 is provided and inserted into the nut hole 48P3. mosquito The collar 52 has a retaining ring #155t which consequently accommodates the locking ring 54. There is. When the collar 52 is fitted, the locking ring has two parts that limit the sliding groove 49. In the sliding groove 49, which is wider than the locking puffer groove 55, at any position between the shoulders of the Sliding.

The upper WK of the collar 52 has an end fitting groove of 5 yen when the collar 52 is forced upward. A wedge 56 is formed to hold the retaining ring 57t. color 52 When forced fully rearward, the retaining ring 57 is radially compressed and the end Attachment applies a pushing force between the tool 3 and the collar 52. At the same time, the retaining ring 57 The supporting structure 40 is prevented from falling off, while the supporting shoulder 58 and the lower shoulder of the end fitting groove 5 Contact t-1a is established between

To release the retaining structure 40 from the body, simply release the retaining ring 57. All you have to do is lower the collar 50t. Protrudes downward beyond nut 47 The flange 53 facilitates the implementation of these movements of forces 2-52 in a very easy manner. enable.

Finally, the valve has its most important parts shown in diagram g3, and the *n part itself. It consists of a 51j body or actuator 70 which is publicly known. The actuator is Substantially the opening is located at the chamfered end 43 of the rod 42, only one of which is shown here. A perforated positioning plate that receives the end of the positioning pin 76 of the V number of the cover 26 Consists of rate 71.

The local pre-nanohen ring arch 72 is fitted into the chamfered sib plate 28 and assembled. during which first contact is made with the remainder of the valve.

The operating member 21 can be actuated via an actuation key or wrench 75, which The end of the wrench is formed in a complementary manner to the end of the key or wrench 30. and its engagement allows the actuation key 73 to slide in the slot 75 and 2 The spring 74 generates a normal force parallel to the common axis of the two keys. Ru.

The valve assembly is schematically illustrated in FIG. The inner W structure 20 is arranged above the main body 1 and Supported by. In the same manner, the actuator 70 is mounted on the internal structure 20. on the inner structure 20 and maintained by gravity on the inner structure 20. Finally, the holding structure 40 is placed under the body 1 and held in place by the collar 32 and the retaining ring 57. is maintained. However, the device is unsuitable69 and therefore cannot be used in normal use. In use, the rod 42 is supported by the locking nut 61 (41t). It is used to maintain a rigid connection between the internal structure 20 and the main body 1. The diameter portion 59 is engaged with the attachment section 35, in which case the locking shoulder 44 is engaged with the cover It is supported on the upper surface of 26. Thus, rod 42 primarily serves as a connecting bolt. Keep the first structure 20 and the second structure 40 firmly at the predetermined position #CIl on the main body 1 do.

In case of maintenance operations, the valves described above will justify the benefits associated with the present invention. 5, which in turn withstands special and simplified disassembly and reassembly. This will be explained with reference to FIG.

During valve removal, the first operation is to actuate actuator 70 as shown in FIG. t-consisting of removing. This operation is performed by the grip that acts on the fitted handle 95. The actuator 70 is moved upward by a remote control arm terminated by a cap 9°. All you need is to ascend. On the other hand, the precentering arch 72 and the chamfered The plate 28 and on the other hand the actuating key 75 and the key 3o are disassembled.

Actuator 70 can then be inspected or replaced.

Will the next process be done in two steps? Take out the 3-part structure 2゜. Ru. Thus, the contact surfaces of the internal structure 2o and the main body 1 are pressed together and separated. The interval control is IE! ! It does not have adequate power to perform the extraction. Holding structure 40 It is for this reason that this is provided.

Loosening the nut 47 also prevents the support plate 41 from rising and therefore the rod 42. Ding. Until now, the screw 42 has been directed downward and contacted and engaged with the locking shoulder 44. The cover 26, which had been closed, now rests against the release shoulder 45 and is raised. During this time Inside, the retaining ring 57 is engaged in the end fitting groove 5 by a wedge 56 and is The nut 47 is integrated with the main body 1.

Following this, the internal structure 20! Il! A final withdrawal will be made. gripper 90 is the handle 921C of the cover 26 in order to reach the state shown in FIG. 8 from the state shown in FIG. and supports rotation in that part. A key placed in advance in the attachment part 35 of the attachment opening 33 The diameter-reduced portion 59 of the rod 42 has a diameter larger than that of the chamfered end 43. It is arranged in the opening 34 at the end. This rotation is described above, and the next release operation is from the positioning bin 6. It is possible to release the cover 26 and remove the cover.

The gripper 90 stands up 9 and then lifts the internal structure 20 upward, as shown in FIG. rise Next, the gripper 9° has a wider range of possibilities than the internal structure 20't. The cover 26 can be separated from the cage 22 in particular by a separate operating tool. You can bring the rice to the operating station. The explanation can simply be based on Figure 1. can. The first step is to loosen the locking screw 31 and the locking screw 27. makes cover 26 and cage 22 non-rotatable. Cover 26 and cage 22 is then grasped and moved as far as possible so that the ring 29 is removed from its recess. in such a way that it can be removed and pulled out after the cap 32 is removed. and rotate.

In order to pull out the operating member 21 from the cage 22, a strip of appropriate thickness is placed on the cage. Place the pacer tube and replace the key 30 at the end of the spindle 37 with the locking screw 31 It is only necessary to lock the ’. An indexing force is then generated on the locking screw 31; This withdraws and releases the operating member 21. Then all wear trends of the internal structure are calculated. the member in the direction, i.e. the a-way between the operating member 21 and the cage 22 on the one hand, and the cage 22 on the other hand. The gasket between the cage 22 and the core 11) can be easily replaced.

In principle, the deordering and maintenance operations mentioned above must be appropriate. deer However, it may be necessary to pull out the main maintenance structure 40 if necessary.

The procedure according to FIG. 10 is adopted. The finger 93 is arranged on the upper surface of the flange 35. The supporting gripper 94, which is integral with the finger 93, is attached to the collar in the hole 48 of the nut 47. 52 is placed above the support plate 41. For the first operation , the finger 93 is pulled down onto the flange 53', which engages the wedge 56. The contact between the retaining ring 57 is then removed and the retaining ring 57 is then moved to the right in FIG. Exit through end fitting #15 as shown in half. Is the main body 1 because of the holding structure? to the tool which is released from the It can be easily transported.

Reassembly of the valve is exactly compatible with the operations described above, in the opposite direction to disassembly. The method that brings about complementary operations is not explained in detail in Gojin. Mere differences are the center The rings and locating pins as well as the rods 42 in the cover 26 must be implemented. This requires slightly more expertise to operate.

Nevertheless, the problem involved is that it is possible to use a specialized Can be easily solved by the gate family.

It should be noted that in relation to the main body 1, the first structure 20 and the S* body 70 are The opposite arrangement of the second structure 40 is such that the second structure 40t - It is very convenient that there is no need to remove the 9th part, and the second structure can be remotely controlled. 40 elements and these elements are isolated so that they are insulated from the rest of the valve. It can be easily approached.

Akcheny/70 and internal structure 20, which are the structures that require the highest maintenance, are In a preferred embodiment of the invention, the device is pulled out and placed by gravity as it rises to the top. This is only explained to you. Other variations are within the scope of the invention as disclosed in the claims. be able to think without deviating from the
